Find 15% of 15% of 15% of 500. How does this compare to finding 45% of 500

2 answers:

6 0

500* (15/100)* (15/100)* (15/100)= 1.6875

500* (45/100)= 225

Therefore, the process of finding 45% of 500 does not have anything to do with the process of finding 15% of 155 of 15% of 500~

15% of 15% of 15% of 500 = 1.6875
45% of 500 = 225

If you want to find 15% of 15% of 15% of 500 then you first have to multiply,
0.15 x 0.15 = 0.0225
then you have to multiply 0.0225 times .15 AGAIN,
0.0225 x .15 = 0.003375
then you finally multiply
0.003375 x 500 = 1.6875

If you want to find 45% of 500 you simply multiply
.45 x 500 = 225

Hope this helps!

A computer programmer charges $45 an hour for a coding projects plus a start-up fee of $150.

Alexus [3.1K]

Answer:

1.)(I cant draw a slope but here is the equation) 45x+150

2.) 25(45) + 150

1125+150

1275

the coding project will cost <u>$1275</u> if the programmer charges $45 and hour, and takes up 25 hours

Are similar polygons congruent?

Vilka [71]

Polygons are similar when they have the same number of sides,
their corresponding angles are equal, and their corresponding
sides are all in the same ratio.

When that ratio is ' 1 ', they are also congruent.

That can happen sometimes, but it doesn't always have to happen.

A composite figure is shown.

VikaD [51]

The surface area of the pyramid is 60 square feet

The surface area of the square prism is 480 square feet

The surface area of the cube is 180 square feet

The total surface area is 720 square feet

<h3>Area of Composite figures</h3>

From the question, we are to calculate the surface area of each part of the composite figure

For the cube

Surface area of a cube is given by

$S = 6l^{2}$

Where $l$ is the length of a side

But only have 5 surfaces of the cube are part of the composite figure

∴ Surface area of the cubic part of the figure = $5l^{2}$

From the given information,

$l = 6 \ feet$

∴ Surface area of the cubic part of the figure = 5 × 6²

Surface area of the cubic part of the figure= 180 square feet

For the square prism

The surface area of a square prism is given by the formula,

$S = 2l^{2} + 4lh$

Where $l$ is the length of the sides and

$h$ is the height

But the <u>square surfaces</u> are not part of the surface of the figure

∴ Surface area of the square prism in the figure = $2l^{2} + 4lh - 2l^{2}$

Surface area of the square prism in the figure = $4lh$

From the given information,

$l = 6 \ feet$

$h = 20 \ feet$

Thus,

Surface area of the square prism part of the figure = 4×6×20

Surface area of the square prism part of the figure = 480 square feet

For the pyramid

The pyramid is a square pyramid

The surface area of a square pyramid is given by

$S = l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h ^{2} }$

Where $l$ is the base length

and $h$ is the height of the prism

But the <u>square base</u> is not part of the surface of the figure

∴ Surface area of the pyramid part of the figure = $l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h^{2} }\ - ( l^{2})$

Surface area of the pyramid part of the figure = $2l\sqrt{\frac{l^{2} }{4}+h^{2} }$

From the given information,

$l = 6 \ feet$

$h = 4 \ feet$

∴ Surface area of the pyramid part of the figure = $2(6)\sqrt{\frac{6^{2} }{4}+4^{2} }$

= $12\sqrt{\frac{36 }{4}+16}$

= $12\sqrt{9+16 }$

= $12\sqrt{25}$

= 12 × 5

= 60 square feet

Hence, the surface area of the pyramid is 60 square feet

Thus,

The total surface area = 180 square feet + 480 square feet + 60 square feet

The total surface area = 720 square feet

Hence, the total surface area is 720 square feet
